Abstract
Patente de Invenção: <B>"DISPOSITIVO DE MANOBRA DE UM MECANISMO DE MUDANçA DE VELOCIDADE, COM VáLVULAS DE REGULAGEM DE PRESSãO PARA A PRESSãO DE TRABALHO E UMA PRESSãO DE ABASTECIMENTO"<D>. Em um dispositivo de manobra de um mecanismo de mudança de velocidade, com uma ligação com fecho devido à fricção, por cujo engate por meio de um elemento de regulagem de meio de pressão torna-se eficaz uma multiplicação de embreagem associada, é usada uma pressão de comando derivada da pressão de trabalho do elemento de regulagem, para influenciar uma válvula de regulagem de pressão para uma pressão de abastecimento, que se forma em uma válvula de regulagem de pressão, que regula a pressão de trabalho na dependência de uma unidade de comando eletrónica.Invention Patent: <B> "SPEED MECHANISM MANEUVERING DEVICE, WITH PRESSURE REGULATING VALVES FOR WORKING PRESSURE AND A SUPPLY PRESSURE" <D>. In a maneuvering device of a gear change mechanism, with a connection with lock due to friction, by which coupling by means of a regulating element of pressure means an associated clutch multiplication is effective, a pressure is used control unit derived from the working pressure of the regulating element, to influence a pressure regulating valve to a supply pressure, which is formed in a pressure regulating valve, which regulates the working pressure depending on a control unit electronic.
